We will be following up with some detailed tutorials as soon as possible on the new Melody plugin.
The basics work like this:
Connect to Chords if you wish. Or, you can use Melody as a standalone tool. Select your key if you're not connecting to Chords (which sets the same key automatically)
Generate notes in a number of ways. Pencil (Click on the grid to add a note), Paintbrush (click and drag to draw multiple notes) or Idea.
Idea involves creating an Idea box, which is a section inside which notes will be automatically input. You can change the borders of this Idea box any time.
Once an Idea has been started you can then alter the notes inside it in many ways - it involves a little trial and error here. Like all sophisticated software, mastering the finer controls takes a little practice, and it may take some getting used to since there is nothing similar on the market.
Pencil and Paintbrush also have interesting parameters that let you choose your starting note, how much of certain notes to generate and so on.
You can also use MIDI editing to manually change notes around, alter lengths etc.
Right-click on a note to delete.
Blue notes are either the Root, Third or Fifth note in the current chord. Green Notes and Yellow Notes can be 2nd, 4ths, 6ths or 7ths depending on the chord itself. They are dissonant in varying degrees, but still, sound cool. Red Notes are highly dissonant and would probably be best avoided. (Rules are made to be broken, of course)
Please bear in mind this plugin is still in Beta and some changes in the workflow may yet be rolled out in the final version :)
